UltraEdit for ruby

1.高级》工具栏配置》
命令行：C:\ruby\bin\ruby.exe -w "%f"
工作目录：%p
菜单项名称：Ruby
选取“输出到列表窗口” 和“捕捉输出” 单击“插入”再”确定“

3.从此地址ftp://www.ultraedit.com/wf/ruby.txt下载ruby语法文件。

4、修改UltraEdit根目录下的wordfile.txt文件，将上面下载过来的ruby.txt里的内容加裁到wordfile.txt末尾。

5、修改wordfile.txt文件，查找HTML位置，将RHTML加到HTML位置的后面，就可以支持.rhtml高亮显示。

OK，所有步骤已经全部完成，如果您也是RUBY爱好者不防也试试。

get_response

require 'net/https'
response = Net::HTTP.get_response('http://www.sina.com.cn','index.html')
puts response.body

ruby抱错了：
c:/ruby/lib/ruby/1.8/net/http.rb:560:in `initialize': getaddrinfo: no address as
sociated with hostname. (SocketError)
from c:/ruby/lib/ruby/1.8/net/http.rb:560:in `open'

不需要http://否则会出错的！

response = Net::HTTP.get_response('www.sina.com.cn','index.html')
这样就可以了。
